Guangzhou, China (May 19, 2025) —Celestion, one of the world’s leading suppliers of professional loudspeakers and compression drivers for sound reinforcement applications, will showcase key products from their pro audio range at the upcoming Prolight + Sound Guangzhou show, in particular demonstrating their flagship high-performance subwoofer, the 24-inch diameter TSQ2460. Also on display are two now-in-production models from the UK-built, neodymium magnet Ten Squared (TSQ) range, the TSQ1845 and TSQ2145. Elsewhere on view is the versatile, high- performing ferrite magnet PowerProX18 subwoofer, the latest 1.4-inch exit compression drivers, including the soon-to-be released CDX14-3035, and the upcoming neodymium magnet CNX0820 common motor coaxial driver, featuring an integral constant directivity horn.
TSQ2460
The Flagship 24-inch TSQ2460 aluminium chassis, neodymium magnet, low frequency loudspeakers are meticulously engineered for use in high powered subwoofer applications including: paraflex and folded horns and bass reflex designs.
The groundbreaking TSQ range has been born out of a specialist development program at Celestion’s UK-based R&D facility, embodying Ten Squared Technology, offering a number of incremental design improvements that together add up to a new standard in LF driver performance and durability. TSQ transducers are assembled on a new state-of-the-art robotic production line at Celestion’s UK-based research and manufacturing facility and represent a culmination of the company’s 100 years’ experience in loudspeaker engineering and the integration of Celestion’s latest feature innovations. TSQ drivers are designed without compromise to deliver consistently superior levels of performance in the most demanding professional sound reinforcement applications, even after hundreds of hours of use.
The TSQ2460 has a remarkable power rating of 2500W (nominal, AES standard)/5000W (continuous) thanks to the enhanced cooling offered by the highly efficient Precision Tuned Venting (PTV) system together with a proprietary voice coil featuring advanced heat-resistant adhesives. The cooling benefit is as much as -80°C, versus conventional designs.
The specially reconfigured magnet assembly allows much greater cone excursion and a remarkably high Xprotection level. The driver’s motor strength and mechanical compliance reach their defined Xprotection limit at practically the same point, achieving a low distortion performance, even during high excursion. This capability is complemented by Ten Squared’s unique, polysiloxane-laminated dual suspension that enables the driver’s suspension system to work much harder without losing stiffness, providing better coil control and a reduced likelihood of DC shift, while simultaneously increasing speaker longevity.
Also on display from the Ten Squared range are the 21-inch TSQ2145 and 18-inch TSQ1845, both meticulously engineered for subwoofer applications.
PowerProX18
The 18-inch, ferrite magnet PowerProX18 subwoofer delivers a relentless high-quality performance that makes it ideally suited to applications including cinema sound, fixed install and touring sound reinforcement.
The subwoofer features an advanced cooling design, developed for ferrite magnet assemblies, that enables its voice coil to run significantly cooler than comparable competitor drivers. This greatly reduces heat-related stress on the 4-inch glass-fibre voice coil former and other thermally sensitive parts. It also reduces the temperature-related rise in Re (coil resistance) that causes power compression. By operating at less severe temperatures, the subwoofer offers end users brand-new-out-of-the-box high performance throughout the product’s lifespan.
With a nominal impedance of 8 ohms, the PowerProX18 subwoofer’s power rating is a mighty 1200W (nominal, AES standard)/2400W (continuous). Sensitivity, measured at 1W@1m in 2π space is 97dB. The Bl (motor force) curve of the PowerProX18 exhibits remarkable symmetry, and thanks to the cone’s polysiloxane-laminated dual suspension, which provides greater stability and improves cone displacement symmetry, the K (stiffness) curve again reveals superb symmetry resulting in notably reduced distortion.
PowerProX18 is designed for longevity of high performance, delivering maximum durability and reliability throughout the lifespan of each speaker. It is intended to surpass the performance of other 18-inch subwoofer drivers in its class, making it ideal for challenging sound reinforcement and cinema sound applications.
CDX14-3035
Celestion’s new 1-4-inch, ferrite magnet CDX14-3035 HF compression driver is an upgraded version of the earlier CDX14-3030 model. Featuring a single piece titanium diaphragm, it is identical in performance to the CDX14-3045. However, it has been built with a ferrite magnet for applications where size and weight are less important than cost considerations.
This high-quality HF solution features a power handling capability increased to 120W (nominal, measured to AES standard)/240W (continuous) and an enhanced sensitivity of 108dB plus lower crossover point of 800Hz (12dB/oct).
In addition, the CDX14-3035 features a 75mm/3-inch diameter edgewound copper clad aluminium voice coil, and 35mm/1.4-inch exit size. The unit features an enhanced surround shape for greater linearity with a high temperature polymer clamp ring that contributes to lower distortion.
The companion models, Celestion’s new neodymium magnet HF solutions, the 1.4-inch exit CDX14-3045 and CDX14-3055 will also be on display.
CNX0820
Shown at final prototype stage, the CNX0820 is the first of a new family of coaxial drivers from Celestion and is scheduled for launch later in 2025.
The unit features a 2-inch edgewound copper clad aluminium voice coil (LF) and a 1.75-inch edgewound, copper clad aluminium voice coil (HF), with the neodymium magnet assembly acting as a common motor for both low and high frequency elements. The device’s integrated constant directivity horn provides 50° dispersion. In addition, the unit features twin demodulation rings to reduce harmonic distortion and a field repairable polyimide HF diaphragm.
The CNX0820 offers a power handling of 250W (nominal, AES Standard)/500W (continuous) and 95dB sensitivity. It is ideal for compact and discreet sound reinforcement applications such as architectural installations where a two-way system may need to be deployed in a small area.
